Good day to all. I am installing a new toilet in a Theta 26 yacht. Can anyone advise on the valve in picture? Don't want to fiddle, it is below the

Welcome to the forum
It is obviously the outlet valve, but never seen one like that in Europe. The "standard" in Europe now is 3/4" BSP ball valve (rather like your inlet) and a 1 3/4" BSP outlet similar to those used in domestic plumbing but made (along with skin fittings and hose tails) in a corrosion resistant brass called DZR or bronze. However there is a trend particularly for replacements to use non metallic valves from a New Zealand company Tru Design which are available in the same sizes. hope this helps.

Yes it is the outlet. This looks like and non-return valve. Its below the water line so I don't want to turn on it too much.
Any idea how one could replace the valve without taking the boat out of the water?

Whatever it is, I would treat it as open rather than closed (Shut off) until you know otherwise. Handle in line with pipe is often but by no means always an indicator that the valve is open.

Tranona, Please excuse my rudeness. Thank you for the welcome . Find this a little challenging for now !
Think you are correct it is open. Do you think it would be wise to try and turn the handle? With a wrench it is a bit tight.

1 3/4" BSP sounds like an unusual size. Perhaps you meant to write 1 1/4", which I think is fairly standard for toilet outlets?

The construction of the valve and fitting looks unusual, so it would be boat out of the water in my view. You could try to beach the boat and do it at low water but you could well run out of time if it goes wrong.

Where was the boat built and does the builder still exist? If so, maybe a call to them to ask the relevant questions.

Valves are normally handle in line with pipe Open. Across the pipe Closed.
Where does the other end of the yellow pipe go?
If it can be disconnected, then disconnect and elevate above the waterline, then play by lowering the pipe into a bucket.

The boat was built in S Africa where the OP is located. Google is your friend - and why I commented that we don't see that type of valve in Europe.inlandsailing.co.za/dtmblog/yachts/theta-26/comment-page-1/

The boat is inland in S.A. Bought it as a project for something to do while retired, now paying schools fees again !
The yellow pipe was connected to a Jacobs Toilet (in very poor condition) above the water level. So stripped it out.
Only get chance over a weekend so will play around with it this coming weekend . Was hoping someone recognized the valve.
so that I could just close it and disconnect the yellow pipe completely. Thanks so far.

Pretty sure if you turn that handle 90 degrees - it may only go one way - that will close it. Easily checked by easing the hose off. If water come in open, so push hose back on or turn the handle back to where it was. Convention is that handle in line with flow means open.

Much of my youth was spent drinking at LDYC, which is just up the dusty road from where your Theta was built. A regular debate at the bar was about the quailty of the build. I'm fairly confident that you'll find that fitting at any decent domestic plumbing supplier.

Its a Spartan Marine seacock, bronze and they are still made in the USA. It appears your seacock is missing the handle which fits over the tap like structure that looks like a gas tap handle.

These tapered sea cocks can sometimes benefit from slacking off the bottom nut a turn and then tapping upwards to help free them .

I knew someone who earned a living fixing boats who regularly changed seacocks with the boat in the water. Not for the faint hearted, but actually not much worse than putting your log impellor in or taking it out.
He did make sure the seacock would come undone from the through hull first and had a suitably sized wooden bung handy, just in case.
